To all whom it may concern: 1

Be it known that I, SAMUEL F. Mites,

a citizen. of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Fireplace Damper, of which the following is a specification.

chimney flue.

With the foregoing and other objects in view which will appear asthe description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention,

Referring to the drawing Figure 1 illustrates asectional view through a chimney showing the invention as applied to the flue thereof.

Figure 2 illustrates a top plan view of the damper and its supporting frame.

Figure 3 illustrates a sectional view taken on line 3-3 of Figure 2.

Referring to the drawing in detail, the damper is shown as installed in a chimney flue of a fireplace, and comprises a rectangular frame having a central opening slightly larger than the sides of the rectangular damper 5, to receive the damper 5 and support the same in proper relation with the flue of the chimney.

The frame includes side members 6 and end members 7, the end members having inclined edges to permit the frame to be wedged between the walls of the flue so.

that the damper may be held within the flue against displacement, there being suit able means not shown, employed in connection with the frame for securing the frame in its proper position.

Each of the end members? is provided wlth a depressedportion' which depressed portions are curved lt'o accommodate the plntles 8 of the. damper 5, and as shown, one of thesefpintles 8 extends through the Patented net; 21, 1922*.

keeper 9 t0 secureone end of the damper to its frame, while. the opposite pintle- 8 is notched throughout a portionofflits. circunr ference, as at 10 to accommodate the right angled end 11 of. the spring member 12,

which hasits rightangled end 13 positioned between the lugs 14, also formed on the frame.

' Thisspring member .12 is 'apertured adjacent its right angled end 13 to receive thebolt-115 which passes through .anppen 111g formed, in the frame, thenut: 16 operating on one end of'the bolt, being provided for tensioning the spring member 12 to normally hold the right angled end 11 into engagement with the notched portion of its cooperating pintle.

From the foregoing it is obvious that this spring member 12 has the double function of preventing displacement of the pintle cooperating therewith, and at the same time restricts rotary movement thereof.

Supported on the damper proper is an elongated connecting bracket 17 provided with an elongated opening 18 and a right angled end portion 19, the elongated opening 18 being provided to accommodate the bolts 20 which extend upwardly through the damper '5 and accommodate the nuts 21 which embrace a portion of the bracket 17 to secure'the bracket to the damper 5.

This operating lever 22 has its inner eX- tremity pivotally connected to the upper end of the right angled portion 19 of the bracket 17, the opposite end of said lever 22 operating through the sleeve 23 to permit the operating lever 22 to freely move within the opening 24 provided in the chimney, to which the device is applied.

On the free end of the operating lever 22 is a handle 25 which handle acts as a stop to prevent the operating lever 22 from iwhat I'claim' as new is 2-- Upon movement of the operating lever 22,

the right angled end of thespring memberv 12 automatically assumes a position within one of the notches of the pintle thereby restricting the movement of the damper 5. In order thatthedamper 5'will be prevented from moving below the side member 6 of the frame, a stop 26 is pl'ovided on'the damper to contact with the upper surface of the side member 6. e

'Having' thus described the invention,

1. In a damper constructioma frame, a

damper supported within the frame, a relatively long bracket member adjustably connected to the damper, and an operating lever H having connection with the bracket member.

frame, a connecting bracket having an elongated opening, vmeans extending through the V damper and lying Within the opening for securing the bracket member to the damper,

and operating means having connection with the bracket for permitting the damper to be moved within its frame. 7 i

4. In a" damper construction, a frame, a damper pivotally supportedv within the fr ame,-said damper having pintles, a pair of lugs on the frame, a spring member having right angled ends, 0ne of said ends being positioned between the lugs, the opposite end adapted to adjustably engagewlth one of the pintles for locking the damper in an adjusted position, means for tensioning the sprlng member, and means for operating the damper; p 7 V In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
